Bump mapped Barrel

This week we looked at bump maps (normal maps). We looked at using nDo for photoshop to create normal maps from images. Here are the normal maps of my barrel:

 

This is the normal map made of the barrel, the long way.

 

Here is a scratched metal normal map created with nDo in photoshop.

 

The grey barrel is the low polly model using the above normal maps, I'm going to practice creating normal maps from high poly models a bit more.
